HopRocket as a Pre Chiller Filter(Without hops)

HI there,

In a few weeks i will have my new system up and running(pics when finished of everything) and id like to use the Hoprocket as a filter.  While sometimes it will be filled with hops as a filter media, other times id like to use a non-hop Filter Material.  I was thinking about using SS Scrubies like used to wash dishes, but was hoping for some Input from people who have tried this first hand.

Any other ideas would be great.
Cheers,
Jeff

I think this was discussed recently. Can’t remember the outcome.

I wonder if an appropriately sized raschig ring would work. They are used to pack still columns. They come in many sizes and would be reusable. Some oils might stick to them.
